Product Summary
The CMMG Dissent Mk4 Complete Upper Receiver is designed for the .22 ARC caliber and features a 16.1-inch barrel with a 1-7 twist rate. Finished in Midnight Bronze, this upper group utilizes a patent-pending direct impingement Compact Action to reduce bulk and length compared to traditional AR pistols. It includes a forward non-reciprocating side charger for quick bolt operation and comes equipped with a 1913 Picatinny rear end plate. This upper is ideal for building a compact carbine or a pistol-style build when paired with a mil-spec compatible lower receiver.
